A system may include a central database configured to store a set of signature brain wave responses as part of a profile of a user. The system may include a transaction device, a sensory device, and an EEG device. When a transaction request is received from the user, the system may be configured to present the user with a sensory prompt, detect a response of the user to the first sensory prompt, compare the response to the signature response in the profile associated with the sensory prompt, and, when the response matches the signature response within a predetermined delta, authenticate and/or route the transaction request.

FIELD OF TECHNOLOGY

Aspects of the disclosure relate to computer systems. Specifically, aspects of the disclosure relate to systems and methods for authenticating and routing digital signals.

BACKGROUND OF THE DISCLOSURE

Digital signals are commonly used to transmit sensitive information. For example, digital signals are often used to transmit requests that may relate to the health and/or finances of the signal initiator. Digital signals that are hacked, co-opted, misrouted, or in other ways defective may jeopardize the health and/or finances of the purported signal initiator.

For example, a digital signal may be received by a financial institution. The digital signal may indicate that an account user is requesting a certain transaction, e.g., a withdrawal at an automated teller machine (ATM). Conventional systems for authenticating the signal may include reading a card and/or entering personal identification number (PIN). Conventional systems for routing the signal may include pressing a button on a keypad or touchscreen.

However, cards are vulnerable to theft or duplication without authorization. PIN numbers are sometimes obtained without permission. Touchscreens and keypads may freeze, stick, or otherwise break. Users, especially the elderly and those with physical or mental difficulties, may enter routing, or other, instructions they do not really intend. Such signals, if mistaken and/or not properly authenticated or routed, may result in funds being withdrawn or otherwise misdirected without permission or intention of the account user.

It would be desirable therefore, to provide systems and methods capable of providing secure authentication of sensitive digital signals.

It would be further desirable for the systems and methods to be capable of accurate routing of sensitive digital signals.

SUMMARY OF THE DISCLOSURE

Aspects of the disclosure relate to secure methods for authenticating and/or routing a digital signal. A method may include recording a set of signature responses of a user. Each signature response from the set of signature responses may include a pattern of brain activity detected by an electroencephalogram (EEG) when the user is presented with a sensory prompt from a set of sensory prompts. The method may include storing the set of signature responses in a central database as part of a profile of the user.

The method may include receiving a request from the user to initiate a transaction, presenting to the user a first sensory prompt from the set of sensory prompts, and detecting, via an EEG, a response of the user to the first sensory prompt, the response including a pattern of brain activity.

The method may also include comparing the response to the signature response in the profile associated with the first sensory prompt. When the response matches the signature response within a predetermined delta, the method may include authenticating and/or routing the transaction.

DETAILED DESCRIPTION OF THE DISCLOSURE

Systems and methods for secure authentication and/or accurate routing of digital signals are provided. The digital signal may, for example, be a sensitive request signal. A sensitive request signal may, for example, be a signal requesting a financial transaction. Other exemplary signals may include other suitable messages or requests, especially ones that, if misdirected or fraudulent in nature, may incur damage and/or loss.

The systems and methods may include a platform. The platform may include and/or be connected to a central database. The central database may be configured to store a set of signature responses as part of a profile of a user.

The set of signature responses may, in some embodiments, be recorded after the user opts-in to use the platform. For example, the user may be provided an option to opt-in via a website or mobile application (“app”) accessible on a mobile device. The website or app may be associated with an entity, such as a financial institution, that is associated with the central database. The user may also, in certain embodiments, opt-in at a physical location of the entity.

Each signature response from the set of signature responses may include a pattern of brain activity detected by an electroencephalogram (EEG). The EEG may, in certain embodiments, be a part of (or otherwise connected to) a user device, such as a computer or mobile device. The EEG may be located at a location of the entity (for example, at a bank location). In some embodiments, the entity may have an agreement with a medical facility to utilize EEGs of the facility to detect the signature responses.

The pattern of brain activity of the signature responses may be detected by the EEG when the user is presented with a sensory prompt from a set of sensory prompts. The sensory prompt may, in certain embodiments, include an image prompt, a text prompt, an audio prompt, a video prompt, a scent prompt, a touch prompt, and/or a taste prompt. The sensory prompt may include an actual physical object. The object may be in the presence of the user, or, in some embodiments, not in the presence of the user. The sensory prompt may be a prompt to think about an object or a concept.

The sensory prompts may be presented by the entity. The sensory prompts may be presented at a physical location of the entity. The sensory prompts may be presented via a mobile device, e.g., via an app provided by the entity.

Detecting, recording, and/or storing the signature responses may be part of a training, or tuning, of the platform. Tuning the platform may train the platform with the brain wave patterns this particular user typically emits when presented the sensory prompts. The brain wave patterns may represent a physiological manifestation of an emotional response of the user to the prompts. Each user may have a unique signature response to the prompts. In other embodiments, any other suitable detectable, unique, bio-signals may be utilized by the platform.

The platform may include a transaction device. The transaction device may be configured to receive a transaction request. The platform may include a sensory device. The sensory device may be configured to present to the user a sensory prompt. The platform may also include an EEG device. The EEG device may be configured to detect brain activity of the user.

In one illustrative embodiment of the platform, the transaction device may be an automated teller machine (ATM). The sensory device may be an app running on a computing device such as a mobile phone. The sensory device may be coupled to the ATM or the central server, e.g., via a cable, Bluetooth, WiFi, or other suitable form of connectivity. In some embodiments, the transaction device and the sensory device may be the ATM. In some embodiments, the transaction device and the sensory device may be the computing device.

The EEG may be any suitable device for detecting brain wave activity. The EEG may include a headpiece. The headpiece may include a plurality of electrical leads. The headpiece may resemble a hood, helmet, headphones, or any other suitable EEG headpiece. The EEG may be connected, with wires or wirelessly, to the transaction device and/or the sensory device. It is contemplated that an EEG capable of detecting brain wave activity from a distance may be provided as a built-in component of the transaction device and/or the sensory device. The built-in EEG may be able to detect the brain activity of the user without contacting the.

When a transaction request is received from the user via the transaction device, the platform may be configured to present the user, via the sensory device, with a first sensory prompt from the set of sensory prompts. For example, the platform may display a picture of a flower. The platform may play a clip of a song. The platform may show a video clip. The platform may, in certain embodiments, direct the user to focus on a physical object apart from the sensory device. For example, the platform may direct the user to focus on his or her hand, or a nearby object such as an apple.

The platform may be configured to detect, via the EEG, a response of the user to the first sensory prompt. A response may include a pattern of brain activity. The platform may be configured to compare the response to the signature response in the profile associated with the first sensory prompt. When the response matches the signature response within a predetermined delta, the platform may be configured to authenticate and/or route the transaction request.

The delta may be a percentage. For example, the predetermined delta may be that at least 95%, or any other suitable percentage, of the pattern of the response is the same as the pattern of the signature response. In some embodiments, the delta may be a confidence score. The confidence score may be the output of an artificial intelligence (AI) engine trained to compare two brain wave patterns and calculate a confidence score of the two being emitted from the same brain.

In certain embodiments of the platform, authenticating the transaction request may include matching the response to the signature response to confirm that the transaction request was transmitted by the user. Once authenticated, the transaction may be executed by the transaction device. In some embodiments, the transaction request may be a request of the user to log-in to a system through which a transaction may be requested. The authentication may validate the log-in, and the user may subsequently be enabled to request a transaction.

In some embodiments, the platform may be configured to route a transaction request. The first sensory prompt may be part of a plurality of sensory prompts presented to the user. Each of the plurality of sensory prompts may be from the set of sensory prompts used to generate the set of signature responses. To accomplish the routing, the platform may be configured to present each of the plurality of sensory prompts in conjunction with a different transaction option from a plurality of transaction options.

The user may generate the response by focusing on one of the sensory prompts that is presented in conjunction with the desired transaction option. The platform may be configured to determine which signature response is a closest match to the response. The platform may be configured to determine which sensory prompt is mapped to the signature response that is the closest match. The platform may be configured to determine which transaction option was presented in conjunction with the sensory prompt. The platform may be also configured to route the request to a central server to execute the transaction option.

As an illustrative example, the list of transaction options may include 1) Make a Deposit, 2) Make a Withdrawal, and 3) Make a Transfer. The transaction options may be shown on a display of a mobile phone or an ATM. Adjacent to each option, the platform may display a different sensory prompt—for example, a picture of a flower next to option 1), a picture of a house next to option 2), and a picture of a baby next to option 3). The user may wish to select option 3), so he or she may focus on the picture of the baby. The EEG may detect brain activity while the user focuses on the baby, and compare the pattern of the activity to the signature responses in the database. The signature responses may also include patterns detected while the user was presented with pictures of a flower, a house, and a baby. The platform may determine that the detected response most closely matches the signature response that was recorded for the picture of a baby. The platform may thus determine that the user was selecting option 3), and the platform may route a request for a Transfer.

In some embodiments, the text of each transaction option (or, in certain embodiments, the mere concept of the option itself) may also be the sensory prompt. For example, the phrases “Make a Deposit,” “Make a Withdrawal,” and “Make a Transfer” may each be part of the sensory prompts that were used to generate signature responses. The user may focus on one of the options, and the detected brain wave response may be matched to the signature responses to determine which option the user is focusing on, and thereby selecting.

In certain embodiments, the predetermined delta may be a first predetermined delta when authenticating the transaction, and a second predetermined delta when routing the transaction. The first predetermined delta may, in certain embodiments, be smaller than the second predetermined delta. The platform may be configured in such a manner because authentication includes comparing the current response of the supposed user to the signature response of the user, both in response to the same sensory prompt. The authentication may be more accurate when restricted to a small delta. In contrast, routing may compare a response to an as yet unknown prompt, to a set of responses of the same user to various prompts. It may be sufficient to determine the identity of the unknown prompt by allowing a larger delta, and determining the unknown prompt based on which signature prompt is closest to the current response.

The transaction device may, in certain embodiments, be an automated teller machine (ATM). The sensory device may, in some embodiments, be a part of the ATM. In other embodiments, the transaction device and/or the sensory device may be a mobile phone running an application.

In some embodiments, the platform may be further configured to hash the response with the sensory prompt to create a hashed signal. Hashing the response with the prompt may include linking the response and the prompt. The platform may be configured to transmit the hashed signal to a central server for processing. In some embodiments, the signal may be processed in the EEG device, the transaction device, and/or the transaction device.

In an exemplary embodiment, the EEG may be configured to transmit the response to the sensory device, and the sensory device may be configured to perform the hashing. The sensory device may also be configured to transmit the hashed signal to the transaction device and/or to the central server (or, in some embodiments, to the central server via the transaction device).

Methods for secure authentication and/or accurate routing of digital signals are provided. A method may include recording a set of signature responses of a user. Each signature response from the set of signature responses may include a pattern of brain activity detected by an electroencephalogram (EEG) when the user is presented with a sensory prompt from a set of sensory prompts. The sensory prompt may, for example, include an image prompt, a text prompt, an audio prompt, a video prompt, a scent prompt, a touch prompt, and/or a taste prompt. The method may include storing the set of signature responses in a central database as part of a profile of the user.

The method may include receiving a request from the user to initiate a transaction, presenting to the user a first sensory prompt from the set of sensory prompts, and detecting, via an EEG, a response of the user to the first sensory prompt, the response including a pattern of brain activity.

The method may also include comparing the response to the signature response in the profile associated with the first sensory prompt. When the response matches the signature response within a predetermined delta, the method may include authenticating and/or routing the transaction.

In some embodiments of the method, the authenticating may include matching the response to the signature response to confirm that the request was transmitted by the user.

In certain embodiments, the first sensory prompt may be part of a plurality of sensory prompts presented to the user. Each of the plurality of sensory prompts may be from the set of sensory prompts. To accomplish the routing, the method may further include presenting each of the plurality of sensory prompts in conjunction with a different transaction option from a plurality of transaction options, determining which signature response is a closest match to the response, determining which sensory prompt is mapped to the signature response that is the closest match, determining which transaction option was presented in conjunction with said sensory prompt, and/or routing the request to a central server to execute said transaction option.

In some embodiments, the predetermined delta may be a first predetermined delta when authenticating the transaction, and a second predetermined delta when routing the transaction. The first predetermined delta may, in certain embodiments, be smaller than the second predetermined delta.

In certain embodiments, the request may be transmitted by the user via an automated teller machine (ATM).

In some embodiments, the sensory prompt may be presented to the user via a mobile device.

The method may, in some embodiments, include hashing the response with the sensory prompt to create a hashed signal. The method may also include transmitting the hashed signal to a central server for processing.

In certain embodiments, the EEG may transmit the response to the device which presented the sensory prompt to the user, and the mobile device performs the hashing and transmits the hashed signal to an automated teller machine (ATM) and/or to the central server.

A secure platform for authenticating and routing a digital signal, the platform comprising: a central database, said central database configured to: record a set of signature responses of a user, wherein each signature response from the set of signature responses comprises a pattern of brain activity detected by an electroencephalogram (EEG) when the user is presented with a sensory prompt from a set of sensory prompts, wherein each sensory prompt from the set of sensory prompts corresponds to only one sense selected from a group of sight, hearing, feeling, tasting, or smelling; a transaction device configured to receive a transaction request; a sensory device configured to present to the user a sensory prompt; and an EEG device configured to detect brain activity of the user; wherein, when a request to log in to a digital transactional system is received from the user via the transaction device, the platform is configured to: present the user, via the sensory device, with a first sensory prompt from the set of sensory prompts corresponding to a first sense from the group; detect, via the EEG, a first response of the user to the first sensory prompt, said first response comprising a pattern of brain activity; identify a matching signature response by comparing the first response to one or more of the recorded signature responses stored in the mapping of the profile of the user with the first sensory prompt; when the first response matches the identified matching signature response within a predetermined delta, authenticating the user to log in to the digital transactional system; receive a second request from the user to initiate a transaction; present a plurality of sensory prompts to the user, wherein each of the plurality of sensory prompts is from the set of sensory prompts and corresponds to only a second sense from the group, and each of the plurality of sensory prompts is presented in conjunction with a different transaction option from a plurality of transaction options; detect, via the EEG, a second response of the user to the plurality of sensory prompts, said second response comprising a pattern of brain activity; determine which other signature response of the one or more of the recorded signature responses stored in the mapping of the profile of the user is a closest match to the second response; query the mapping with the other signature response to determine which sensory prompt is mapped to the other signature response; determine which transaction option was presented in conjunction with said determined sensory prompt; and route the second request to a central server to execute said determined transaction option wherein one of the first sense and the second sense is the tasting.
 9. The platform of claim 8, wherein authenticating the transaction request comprises matching the first response to the signature response to confirm that the transaction request was transmitted by the user.
 10. The platform of claim 8, wherein the predetermined delta is a first predetermined delta when authenticating the transaction, and a second predetermined delta when routing the transaction, and the first predetermined delta is smaller than the second predetermined delta.
 11. The platform of claim 8, wherein the transaction device is an automated teller machine (ATM), and the sensory device is a part of the ATM or is a mobile phone running an application.
 12. The platform of claim 8, further configured to hash the responses with the sensory prompts to create a hashed signal, and transmit the hashed signal to the central server for processing.
 13. The platform of claim 12, wherein the EEG is configured to transmit the responses to the sensory device, and the sensory device is configured to perform the hashing and to transmit the hashed signal to the transaction device and/or to the central server.
